Hi

Using 1680x1050 in here on Mac Mini - no problems at all.

Was using a wireless mouse from Microsoft - was working fine. But i presume there migh be some devices which won't work.

My Mini is overclocked from 1.5 to 1.83 - no problems at all. Under MorphOS the fan is much more quiet than under OSX.

I would recommend VERAX cooling system - it's lovely quiet:
